Construction by Contour Crafting using sulfur concrete with planetary applications

Purpose This paper aims to report on the experiments with the Contour Crafting Automated Construction process using sulfur concrete as the choice of construction material. Design/methodology/approach Several experiments have been performed at centimeter and meter scales. A finite element analysis simulation model for the behavior of sulfur concrete-based structures has been developed. Experimental results were compared with the results of simulation. Findings Sulfur concrete has numerous terrestrial applications and is potentially an ideal construction material for planetary construction. Originality/value Experimental samples of sulfur concrete were fabricated using a novel mixer/extrusion system. The mechanism was proven to be durable and stable after more than 500 h of work.
